sometimes get left out of all the "casual" conversations that the colleagues have in the office

Sorry but are people who all come together to work within talking distance of each other the ones at fault because that can actually talk to each other?

Think remote people don't realize how frustrating and time consuming it is to work with them sometimes and it's ALL for their benefit, no one in the office gets any benefit out of them not being in the room.

The real joke to me about talks to improve Twitter is it's not the great unwashed making Twitter a cesspit, it's mostly the bluechecks and Twitter power users it spends most of it's time trying to please that make it an utterly awful corner of the internet.
